Are these cheap Infinity mirror fans any good? Lian Li SL-Inf alternative

Over on my Discord Lord Tim the Great pointed out these fans to me and I was curious. These are basically clones of Lian Li's SL-INF unifans, but at a much cheaper price. Where the Lian Li fans will cost you around £90/$90 for a pack of three, these fans cost just £30/$30.

Too good to be true surely? So I bought a bunch of the "TZMRIT Interstellar" fans, both in standard blade and reverse blade versions and put them inside the Hyte Y40 to see how they got on.

I'll be honest, I was expecting them to be absolutely terrible. But they really aren't. Sure, the feel cheap, the connectors are stiff and the pins bend easily and they have a lot more wires to deal with but they're also significantly cheaper than the Lian Li Infinity fans so what's the deal?

Well, they're quiet as standard, but definitely louder under heavy load. The RGB effects won't be nearly as good and will be motherboard software dependent. They're also flimsy. BUT the lighting is superb. They seem well build in that the fan blades weren't wobbling or making weird noises. They actually have larger RGB mirrors than the Lian Fans and, did I mention they're cheap?

i bought them, put them in my Montech sky two and replaced the original Montech ones, less cable management, the original Montech rgb hub works fine with them too, im very happy with them, btw, i also sold the original Montech fans to cover the cost of these ones, even happier, much happier.

[GeminionRay]

I have 3 fans that look pretty much the same as the ones you have. The model is called Jungle Leopard S12025. I paid for less than $18 total and I couldn't be happier, since they are durable and quiet enough for my need, while making cable management a lot cleaner and easier for just 20-25% the price of Lian Li/Phanteks/Corsair equivalents. My only complaint is that these fans have no RGB-less cable, so I end up with the RGB cable unplugged within the case. Other than that they are great and I can definitely recommend for people who want Unifans on a budget.

[ThatOnlyDev]

Just got mine today, they are very stiff to clip together first time. everything else is extremely easy and neat, the rgb isn't too bright, buying some more now to deck out my whole Lian Li O11 Dynamic case!

[danielwu]

It is possible that the fake ones are not actually fake but just the OEM that Lian Li buys from and slaps its logo on it with some additional modifications. Lots of AIO manufacturers are like this, using Asetek pump designs like Corsair, NZXT, Thermaltake.

[bdybgz]

i own 3 sets of these, 1 set of reverse flow and 2 sets of normal ones, so far they have been fantastic, build quality for mine was decent and lighting was very good, would recommend these to anyone who weas interested.

[viperrcr]

As tempting as they are, I think I would still stay with the Lian Li for the better quality. I really do not enjoy the thought of undoing my cable management and redoing it to replace defective fans when they break down which would likely happen much sooner that with the Lian Li fans. I'll take the quality and quietness of the Lain Li. I'm sure Lian Li fans fail too but I'll hedge my bet with them.

[Daddyezee]

I have the Icoler both S and R i was the 1st person to review them and show how they work if you want control of all your rgbs + motherboard, keyboard, mouse, Ram, AIO, GPU, use SingalRGB I use the IColer fans in both my builds love them fans

[RafaelsDPrintLab]

I bought exactly this fans for my new pc build. Thank to you I also bought the razer rgb controller, thanks for this tip!👍🏻

[HekaWaset]

I made a new build a few month ago in which I had 3 of those in reverse blade at the bottom and one normal blade as exhaust. I also had 3 original Lian Li infinity on the AIO as top exhaust (As well as 2 140 TL LCD on the side). They might look a lot like the Lian Lis at first glance, but there are worlds between them. Even lookwise once installed, you could immediately see the difference between the top and bottom fans. Less LEDS with less elaborate sequences. Performance wise they run a lot louder than the original. Not a big deal up to 40%, but anything above that and they get really LOUD! Also, as the Prawn is saying, the difference in built quality is day and night. 2 months into my new build i caved and bought 4 addition Infinity fans to replace these. Still, you get what you pay for and for that money those are not bad, far from it actually, just don't expect them to perform similar just cause they look similar.

[OriginalBosss]

Maybe it's just me but the fake ones are even brighter? I got the real Lian li infinity fans and they are rather great but i seriously would consider getting the fake ones if the real ones ever fail

Great video thanks for bringing it to my attention!

[AlexanderPama-btje]

One alternative to Lian Li I encountered was the Gamdias Aeolus P2. I haven't seen any reviews on it as well, but I know that Gamdias is also a known brand in the gaming PC market

[bluefire]

Just bought 6 of these costing under the price of what I’d be paying for 3 lian li fans. Crazy price difference I’m just hoping there worth it for now. Down the line I plan to get the actual lian li infinite fans but at the minute I can’t justify that price just for them to look good, these clearly do the job and I’ll be happy if they last me just until I can save enough for aesthetic upgrades in the future.

[shaunmaxwell]

I have the sl uni fans and love them. But would also love a cheaper option for just different options. Love the video

[scyzorpl]

I had lianli fans and one of the fans died in 4 months lianli send me a replacement but after some time the led strip started to burn out so i switched to cheap aliexpress fans that i've got 6 of them for 30 $ prism pro 4 and they are amazing

[welshinu]

i am running 9 similar fans to yours and for the price i think they are great ( i can zero rpm them ) 6 case running at 580 -600 rpm and 3 on aio running at 650 ish allowed to change with cpu temp set fan curve in bios then also in MSI Center. 👍👍

[voidfoxx]

yeah, could be that they come from aliexpress which is overseas so hard (maybe?) to go after. Seems like they found a cheap way to reproduce the lian li

[clay_]

Since so many people have Lian Li fans, it would be helpful and interesting if you were able to do a performance comparison of the different presets of Fan Curves in L Connect - quiet, StdSP, HighSP, etc
